This is not specific to any one locale. The updater reads its UI strings from a file named updater.ini but that file does not contain translated strings in our Tor Browser builds. Unless I am mistaken, this bug has existed in Tor Browser for a long time: the method we use to create language-specific packages relies on including the correct Firefox ESR language pack, but the updater does not read strings from a language pack.
I am not sure how to obtain the correct updater.ini files; we will need to look at how those are generated during Firefox's localized builds.

Doe anyone know how resources "flow" from Pontoon into Firefox? Maybe there is some intermediate place between Pontoon and the final packages where we could obtain the correct updater.ini files.
Probably should be taken over and directly integrated to Tor Project and to be put on Transifex for translating same as was with the case of "onboarding.properties".

I disagree. The reason we "took over" the onboarding properties is because Firefox no longer uses them. We would prefer to let Mozilla own the translation process for strings that are still used by Firefox.
I have said that because Mozilla from unknown reasons didn't include it in, even the string is translated more than 3 years ago. That was the strange thing.
